Kmq-LL' A TTORNEY Patented Sept. 4, 1945 L MooRING DE C E Y AlbertBaliman, United-States Navy (Granted'under 1 the act amended 4April 30,1928 This invention relates to mooringA devices and particularly to suchdevices -for'securingwplanes to'aireldand carrier landingstrips and run'One object Vof lthis invention is to provide a mooring post wherein theeye, loop, hook, or other retaining means through which a cable, line,or snap-on device is attached may be kept free from dirt, grime, or iceand hard-packed snow and sleet.

Another object is to provide a mooring post so arranged that theretaining means will be flush with the ground, thus eliminatinghazardous obstructions to aircraft, vehicles, and personnel.

Another object is to provide a, weather-proof mooring device so arranged'that it may be used in all climates.

Another object is to provide a mooring device that will withstandtensions of about 200,000 lbs.

per square inch. f

Another object is to provide a mooring device having the above mentionedadvantages and yet be of inexpensive and simple construction.

Further objects and advantages of this invention will be apparent byreference to the following description in connection with theaccompanying drawings, in which Figure 1 is an exploded side view,partly in section, of a preferred form of this invention,

Figure 2 is a side view showing the parts partially assembled,

Figure 3 is a side view of the device assembled, locked, and installed,with the cable loop extended ready to receive a cable, rope, or snap-ondevice,

Figure 4 is a side view of the device assembled, locked, and installed,with the cable loop retracted into the mooring device, and

Figure 5 is a top plan View of a, stud which forms a part of the deviceof the invention.

Referring to the drawings in detail, Figure 1 shows the mooring deviceas consisting of a hollow housing in the form of a cylindrical pipe Ihaving an inner threaded portion II at one end and an outer threadedportion I2 at the other end. A threaded cap I3 having an edge I8 isscrewed on to the end having the outer threaded portion. -The edgeportion I8 forms an abutment providing a holdfast means for the pipe IIJwhich is imbedded in a rm foundation such as, for example, concrete,asphalt, or other suitable material. It is obvious that retaining meansother than that shown in the drawings may be used to aid in holding thepipe or housing I0 in the foundation in which it is buried such as, forexamthe eye of the loop offMarch 3,'l 1883.as

The recesses are made large enough to accommodate, without toomuch play, a steel cable welded or soldered at its ends to form a loopI'I. A fairing, bevel, or taper I 6 is formed on the inner portions ofthe recesses I5 to permit the steel cable to be practically flush withthe stud I4 when the cable is pushed down into the pipe, as shown inFigure 4. The inside of the hollow pipe may be packed withgraphite-grease, or other suitable waterproof `lubricating material.

In operation, when the mooring post is in use, I'I is extended toreceive a line, cable, or snap-on device. When it is not in use,however, the loop may be -retracted into said post so that noprotuberance remains above the runway.

Should the steel loop I1 be cut or an overriding vehicle due to failureto insert the loop into the pipe I Il, the loop is readily and cheaplyreplaceable. However, it would require a very hard, sharp, and heavyobject to cause any appreciable distortion or damage to the loop.

The use of thethick lubricant such as, for example, graphite-grease,will permit the steel loop I1 to slide in and out of the'recesses I5without too much eiort and will effectively prevent clogging from dirtand ice. What little ice does form in the space between the slots andthe steel loop is easily chipped off when the loop is lifted out of thepipe. The grease packing need not ordinarily be changed within a periodof one year or more, depending upon the climate and the amount of grimeand dust that collects on run? ways.

A suitable acid-resisting material may be applied to all the outsideparts of the mooring post.

The invention may be used to moor boats, ships, and heavy industrialequipment. It may also be used in places where, for aesthetic or otherreasons, it is best to bury the mooring means when it is not in use. Themooring means, as shown in the drawings, is the extensible loop,

though other means similar to the loop can be used.

It is to be understood that various modifications and changes may bemade in this invention without departing from the spirit and scopethereof as set forth in the appended claims.

damaged byv The invention described herein may be manufactured and usedby or for the Government of the United States of America forgovernmental purposes without the payment of any royalties thereon ortherefor.

What is claimed is:

1. A mooring device adapted to be imbedded in a solid medium andcomprising a hollow housing provided with retaining means for saidmedium and an inner threaded portion at one end; a threaded memberengaging said inner threaded portion and positionable substantiallyflush with the endof said housing, said member having longitudinalrecesses therein, and an extensible loop engaging said recesses of saidmember and movable into and out of said housing.

. 2. A mooring device adapted to be imbedded in a solid medium andcomprising a hollow housing provided with retaining means'for saidmedium and an inner threaded portion at one end, a

threaded member engaging said inner threaded portion, said member havinglongitudinal recesses diametrically disposed therein, and an extensibleloop encircling said member in engagement with said recesses and movableinto and out of said housing.

3. A mooring device adapted to be imbedded in a solid medium andcomprising a hollow housing provided with retaining means for saidmedium and an inner threaded portion at one end, a threaded memberengaging said inner portion and positionable substantially ush with thetop of said housing, said member having bevelled recesses diametricallydisposed therein, and an extensible loop engaging said recesses of saidmember and movable into and out of said housing.

4. A mooring device adapted to be imbedded in a solid medium andcomprising a hollow tubular housing having an inner threaded portion atone end and an outer threaded portionat the other end, a anged elementscrewed onto said outer threaded portion, a threaded member havinglongitudinal recesses therein, said threaded member engaging saidthreaded inner portion and positionable substantially flush with the topof said housing, an extensible loop engaging said recesses of saidthreaded member and movable into and out of said housing, andlubricating means substantially filling said housing when said loop isretracted or extended.
